CONVERTIBLE SOFA.

leali 'Le/wm 'it may concern.' l Beit known that I, FRITZ Il. ANnnnN, a@t tizen ot' theUnited States, resif'ling at the lcitypof Chicago, inthe county ol Cook and Sta'tedot illinois, have invented a new andiisciul Improvement in Convertible Sofas, .lot which the following is a.specication. i' i My invention relates to those combination `-articlesof furniture in which a. sofa having vatully.upholstered seat may beconverted `into a ybed equipped With a separate and @complete set o'tsprings.` lly implying the principles of my inven- `tion the bed-frame,together with the spri1igs,inattress and bedding may be folded `andlowered into the body of the sofa nnderthe upholstered seat. This isdone by `the',movement of the seat itself, and in like manner themovement of the seat in the other direction raises the said bed intopositiOnv lier lise. Then the bed is in use the fa seat isfreversedunder the bed-frame. hecefnstruction is simple and inexpensive. deyiceisprovided which, when the movable parts are actuated in either direction,the initial movement is aided and the final ,movement retarded. n."lhe.` principles of my invention are illust-rted in the drawings inwhich- Figure l vshows across section ot' one form of device lookingfrom the center towardthezend when Opened to be used as a lied 2 is asimilar view of the same -)v rftolded for use as a sofa. Fig. 3 is a .w'similar to F ig. l. of. a modified form ot .the pparatns. Fig. 4 is a'view ot the modiediorm when folded' for use as a sofa. fig. :shows themodified form partly ropened; Fig. 6 is a cross section on line (5-6(df: llg. 4. @lny describing this invention it is to be assumed that thecross sectional end views ,represent one end of the piece of furniture,ftlieother end having a duplicate construc- "tion, and the movable partsof the two ends beinghframed together by connecting bars as indicated.

lFurther describing my invention with reierence to the drawings, inwhich like figures of ret'erence denote like parts throughout: llrepresents the end of the body portion ol oa Oit` substantialconstruction. 2 represents the trent or finishing piece of the same.Toztnhe latter the seat portion 3 pivof ed by a hinge whiclrconsists ola strap attached Specification of Letters Patent.

to the front piece of the sofa body, a. similar strap -5 attached to thecorresponding finishing piece of the sofa seat, and the two 'attached bya connectingpiece (3 provided with loops through which pint'les arepassed to engage with said straps and form a hinge with a double joint.The frame-work of the bed includes engl rails 7 sup}' ortcd by thestationary portion of the sofa, and S attached to the swinging or seatportion. The rail, 7 is supported in the position shown in Fig. l bye'ank levers t) and l() which arc pivoted at, their upper endsl to therail and at their lower ends to the sot'a body. The crank lever 9 isextended downwardly from the lower pivot to torni a` short. arm'll, towhich is attached a spring ll connected with the shift lever 12 pivotedto the sofa. body at 13. The end rail S is pivotally attached in amanner similar to thatalready described by means o the crank levers letand 15 to the inside ot the seat portion of the sofa. Crank lever 1,4has a lower arm 14 which at thel point'y ot greatest. extension restsagainst a stop 1t. The

crank lever 15 has a short arm l5 and a connecting rod 16 is pivotallyattached to the lower extremity thereof at one end, while the other endhas a similar pivotal attachment at the point 17 at which crank leverl() is attached to tne end rail 7. Longitudinal bars 18, 19, 2O and 21connect the construction thus shown to the similar construction which ismounted within the other end of the sofa, and on the frames thus .formedand attached to the end rails are stretched spring mattresses whichmaybe of the woven wire type or of wire mesh having their ends providedwith the spiral springs Q2, 23.

t hen the parts described are in the po sition shown in Fig. l and theouter portion of the swinging portion is lifted, the spring l1- beingunder tension and acting through the crank lever 9, the end railv 7, andthe connecting rod 16, aids in the initial portion. of the li'ft. rl`heapparatus on the stationary portion begins to revolve on the pivots 9.10 under the tension of the spring and later under the intiuence ofgravity until the swinging portion is nearly vertical. At this point theend rail S will drop from its own weight., Jfolding itself` on theswinging part as shown in Fig. At about this point the end ot theconnecting rod 1G will strike` the rob lment ot' end rail. 'T

short end l2 of the lever l2 and turn it on the pivot 13 until it takesthe position in which it appears in Fig. Q, at which position the springis in. such relation to the short arm l1 of lever 9 that the tensionthereot will beiexerted to retard the moveand the connected parts as thewhole swings into the position shown in l`ig. 2. lt will be observedthat the double joint hinge provided at the upper part for folding theso'la seat proper and the lower joint thereof permits the seat with itsattached apparatus to swing iii until the front or linishing piece, bothot' the seatV and ot' the stationary portion, are in line.

- ln the modilied form shown on Sheet 2 the parts are hinged togetherand vthe construction ot the devices in the stationary part of the couchare precisely as described, so also the end rail 8, the crank lever l5and the connecting rod lti. The second crank lever however, may bedispensed with on the movable part of the couch, and the end rails 7 and8 are pi votally connected by a bridge piece at their adjacent ends. Theends ot the woven wire or other mattress are attached to this bridgepiece. The rigid alinement of the end rails 7 and 8, and the bridgepiece 25 is eii'ected by means et' the member 2G pivotally attached at27 to the end rail 8 and the members 29 pivotally attached at .30 to theend of the bridge piece 25. Membei has a right angle flange 2G andmember 2t) has a right angle flange 29. The two are pivoted together at31. l/Vhen the bed sections are extended as in Fig. l lilange 26 restsupon the top of the end rail 8. Flange 29 rests upon the top orp thebridge piece and also upon. the flange 26. It will be noted that themembers 26 and 2) pivoted together as shown form a toggle joint which,when extended, holds the end rails and the connecting bridge piece 25 inrigid alinement.

When this device is folded the end rails as shown in Fig. 4t are spacedfrom each other by the length of the bridge piece 25 and the member 26.

In both forms of the device it will be seen that the action of the hingeconneetiiig the two parts is the same, viz., that when the parts arefolded together the front finished pieces of the movable and stationaryparts of the sofa are in alinement. AWhen opened the faces ot these twopieces are out 'of Contact by the swinging of the hinge on the lowerpintle. That this may be positive a cam device is provided on the lowerpart of the crank lever l0 by setting the lower pivot l0 close to theend and to the inner edge of the saine. When the crank lever is turnedto the horizontal posit-ion, the sota portion beingi'iei'lieiirliciilar, ythe hinge will be lrced and then permitted toswing inwardly as shown in Figs. 5 and when extended so that the i solaportion approaches the horizontal and the crank lever approaches thevertical, the hinge will be forced out by the cam as shown in li`ig. lso that the two finished pieces 0f the front will be out of contact.
